Dustless Chalk 72pcs, Red

By far the best chalk to use on the lousy chalkboards in our large auditorium classroom. Very visible, low dust, and they don't break while writing. I can get through about two hours of lecture with one piece, and I'm writing pretty much constantly. There wasn't a single broken piece in the box that I received. The only bad thing that I've noticed is that, every once in a while when the piece is getting small, small chunks will break off while writing. But that's very rare.

My class likes doing work on their science lab desks with chalk. Buckle in for a dramatic story: I began the year and found a box of chalk left by my predecessor and had been using it. I got more chalk through the school and it was crayola an du septic, and it is TRASH (see top line of photo). I knew I just needed to order more of the other brand, which shall remain nameless. Why? Because it is the best chalk ever made, but they seemed to have stopped making it in the SEVENTIES, and I am gatekeeping it from you good people. See bottom line of photo for the most perfect chalk ever. Distraught, I went to Amazon to find a replacement and found this. Lab tables are less writeable than chalkboards, so they require softer and more pigmented chalk. I was explaining my chalk woes to other teachers and one gave me a piece of Hagoromo. See the photo for the comparison. This brand is very similar! It writes well. My second photo demos what all of the chalks look like after one (1) swipe of an eraser (not back and forth) to give you an idea of eraseability. All of them erased very well once I gave it a couple more swipes.Hope you enjoyed this journey with me. Happy chalking!

ALL BROKEN

Wide stick, coated to help limit dusty fingers and has a nice feel while writing: Lines are clear. This chalk does not scratch or mar the board surface.Are you looking at this as a replacement for Hagoromo?: Rikagaku chalk has a slightly smaller circumference and is about 1/2 inch shorter than Hagoromo. It is packed in plastic trays, rather than nestled in little foam beds like Hagoromo, so there seems to be more breakage in transit. Also, I can't explain why because I'm not a chalk production expert, but this chalk is definitely dustier than Hagoromo.Overall, if you're a chalk nerd like I am and found Hagoromo chalk oddly satisfying ... I think you'll derive nearly the same feeling from Rikagaku.

I was reluctant to buy this chalk due to sooo many reviews of the contents on one color or another arriving broken. But - EVERY piece was intact. The box itself was taped shut & wrapped in a layer of bubble wrap. There is a very light coating on about 3/4 of ea stick, a light wipe of the stick with a soft cloth removes the dust from it having some chalk dislodged in shipping, so you can handle the chalk w/o dust getting all over your hands after wiping it off - and it's good chalk! Writes smoothly.

Horrible it clay not dustless

Previously I bought into the hype of Hagoromo chalk and used that for a few years. I use about 100 pieces of chalk per year. This chalk here is actually way better than Hagoromo. It leaves less dust on your fingers. Less dust falls to the ground when you're writing on a chalkboard. Hagoromo leaves a huge mess on the ground. This chalk is even way cheaper. It's packed better too and less likely to break in shipping. Overall, if you're looking for an alternative to other fancy chalks out there, this is the way to go.

The chalk is very nice. Writes smoothly but the package was packed very poorly and almost all of the chalk is broken into 2 to 3 pieces.

普通に良い商品です。最初にカラーのセットを買ってしまって白がないという致命的なミスを犯しまして改めてホワイトを注文しました。ダストレスで、手も汚れず、これだけ入っててこの価格は安いと思います。

とても使ういやすかった。

good

学校で使用していますが，普通のチョーク（〇ゴロモ）だと黒板が消えにくくなったり，湿気を含むと折れやすくなったりというのが気になっていました。このチョークに変えてから，黒板に板書するのも苦ではありません！
